In a posting on her blog findingmymojo.com, Los Angeles-based Rochester hit back at season one Biggest Loser winner Adro Sarnelli for comments he had made about Rochester, apparently calling her ‘‘massive’’ on Facebook (in a post that has since been deleted).

Under the headline: ‘‘It’s time to cut the crap!’’, which paraphrases a Biggest Loser tagline ‘‘It’s time to cut the fat!’’, Rochester calls Sarnelli’s recent online comments (since deleted) ‘‘disgusting, pathetic and sad’’.

As her tirade continued, she claimed the show’s producers allegedly allowed him to weigh in ‘‘behind closed doors and a few days before filming so contestants had time to recover and look healthy’’. She also said that another contestant allegedly ‘‘drank bottles and bottles of tea tree oil’’ to lose weight. She summed up: ‘‘I would much rather have a large arse than a small mind like yours!’’

Both Network Ten and Fremantle Media, who produced The Biggest Loser at the time of Sarnelli’s win, have refused to comment.

A spokesman for the Australian Tea Tree Industry Association said that people should not drink "bottles and bottles of tea tree oil" as suggested by Rochester as tea tree oil is classed as a poison.

"Tea tree oil is only for topical use only and must not be ingested even is small quantities. It is not a weight loss remedy. Please follow the instructions on any medicinal packaging," he said.
